embossed, punctured, or perforated to form the record.

The invention is designed to make the record by means of the action of a pair of electromagnetic devices which act upon the tape in parallel lines to record the characters thereon in two parallel series. This is well understood and has been illustrated in patents before granted to me.

While the invention is, as above indicated, of more general application, it is specially intended to accomplish the perforation of tapes which may be' either so prepared or perforated for transmissions in automatic or chemical telegraphy, or such perforations of or record upon the tape may be accomplished from adistance through the medium of asuitable circuit, and in that event the tape may be the final record or may serve for retransmission into another circuit.

The special object of the invention is to cheapen and simplify construction and improve operation. To this end the armaturelevers of the recording, punching, or perforating magnets are caused, by means of a mechanical switch acted upon successively by the two armature-levers, to open the circuit of one magnet after, it has been energized to perform its operation and transfers the circuit to the companion'magnet' This may be accomplished in a variety of ways, several of In Fig. 1, a is a-battery or suitable source of electrical energy, 6 a Morse key, and 0 0 its front and back stops. One pole of the battery is connected by wire (2 with the vibratablearm 6 of a three-point switch, of which f and g are the. contacts. The contact g is connected by wire it through the winding of punching-magnet with the backstop 0 of the key. The other switch-contact f is connected by wire j through the winding of punch-magnet k to .the front stop 0 of the key, which is the position shown in the diagram, the contacts a f of the switch being closed, but the circuit of the punch-magnet it is open at the key. If now the key be depressed, the circuit will be closed, the magnet 74 energized, and its armature-lever lrattracted, driving down the punch In this movement the end of the armature-lever acts upon one of the angularly-disposed parts of the switch-arm e and opens the contact a f, deene-rgizing magnet 70 and closing the contacts e g. When now the key is raised and the circuit completed at its backstop 0, the punch-magnetic; is energized and the described operation repeated. In this arrangement frictional contact of 6 with the contacts f g is relied upon to maintain the arm e in position.

In Fig. 2 the arrangement is in all respects the same, except that the contacts f g (corresponding with f g) are shown as adjustable screw-contacts working in the legs of a permanent magnet m, the magnetic attraction upon the iron arm 6 of the switch serving to retain it in either of its twopositions.

In Fig. 3 the contacts f 9 (corresponding with f g) are ordinary adjustable contactstops, between which the switch-arm 6 works. In this arrangement, however, the upper end of the switch-arm carries a small roller n, upon which bears a Hat spring 0, serving to retain the arm in either of its two positions. In Fig. 4 the arrangement is the same as in Fig. 1, exceptthat instead of the angularlydisposed extensions of the switch-arm that arm is prolonged beyond its pivot and provided' with a cross piece or head 10, against which work adjustable screws 9, carried in the ends of the armature-levers.

In Fig- 5 the switch-arm is provided with a cross-head 10, against which the hooked upturned ends q of the armature-levers Work. In this case, however, the upper end of the switch-arm is provided with a cross-head r, having at each end springpieces s, which contact against adjustable contact-screws f 9 working in lateral extensions of the permanent horseshoe-magnet m.

The operation in all cases is obvious, and it is the same as that described in connection with Fig: 1.

In Fig. 6, t is a neutral relay operated from a distance by currents received over the line :20. Its armature-lever 5 corresponds with the key Z) in the other figures. It is biased by a spring and plays between the adjustable contact-stops g, which correspond with the contacts f g, &c., above mentioned.

In Fig. 7, 10 indicates a polarized magnet or relay to be energized from a distance by currents received over the circuit to. Its armature-lever 6 which corresponds with the Morse key already described, plays between the adjustable contacts f 9*.

I claim as my invention- ,1. In a telegraphic tape recording apparatus the combination of two recording-magnets, their armature-levers,asource of energy, the circuits in which the magnets are included, a magnetcontrolling key or lever and a mechanically-operated switch actuated on the energization of the respective magnets to open the battery-circuits of the magnet last energized and to complete the battery-circuit of the other magnet.

2. In a telegraphic tape recording apparatus, two punches arranged to perforate a paper tape in parallel lines, their respective magnets and armature-levers that actuate the punches, a source of energy, the circuits ol the respective magnets, a circuit-controlling key or lever and a mechanicallyoperated switch actuated by the armature-levers of the respective magnets to open the battery-circuit of the magnet last energized and close the battery-circuit of the other magnet.

3. In a telegraphic recorder, the combination with its magnets, of armature-levers for making the record, a mechanically-operatcd switch controlled by said levers, a source oi? electrical energy, and a circuit-completing member by which said magnets are energized through the contacts of said switch.

4. In a telegraphic recorder, the combination with its magnets and recording-levers, of a source of electrical energy for operating said magnets, a circuit-completing member for completing the circuit of said magnets and a circuit-controlling switch mechanically operated by said levers for breaking the circuits of said magnets.

In testimony whereof I have hereunto subscribed my name.
